Inventor: JOLLY DOUGLAS J
IPC: C12N15/867
Filed: 1996-04-19
Abstract: L'invention porte sur des compositions et méthodes permettant d'introduire ex vivo de l'acide nucléique dans des cellules T, dans des cellules non mitotiques et dans des cellules résistant aux techniques usuelles de transduction, par l'intermédiaire de préparations rétrovirales de recombinaison à titre élevé. Les produits de recombinaison du vecteur porté par les particules du rétrovirus de recombinaison codent pour la production d'un ou plusieurs produits géniques désirés d'un ou de plusieurs gènes d'intérêt correspondants dont l'un au moins a des applications thérapeutiques. Lors de leur réintroduction dans un patient, les cellules transduites produisent le produit génique souhaité en quantité suffisante pour traiter un état pathologique particulier.
Patent CA-2217150-A1 (CA)
Title: Deflection monitoring system
Inventor: CANTY JEFFERY N
IPC: G01M99/00
Filed: 1995-04-03
Abstract: Deflections in support structures (30) due to external stress factors, can be detected by a series of laser beams (16). A laser (12) is positioned at the perimeter of the structure (30). The laser (12) generates a laser beam (16) along a path adjacent to the structure (30), and the beam (16) strikes a receiver (14) across from the laser (12). Solid target blocks (22) are positioned along the support structure (30). When deflection occurs in the support structure (30), the targets (22) are concurrently displaced into the path of the laser beam (16). The receiver (14) registers the break in the laser beam (16) and activates an alarm. Each beam (16) is set to detect deflection in the structure (30) within predefined zones and the alarm indicates the zone in which the laser beam (16) path was broken by the deflection.

Filed: 1996-06-05
Abstract: A transdermal composition is disclosed which contains a blend of one or more polymers, one or more drugs, at least one of which has a low molecular weight and is liquid at or about room temperatures. The composition is substantially free of water and liquids which have a normal boiling point (a) optionally below processing temperatures and (b) greater than or equal to the temperature of the low molecular weight drugs.

Patent CA-2225005-A1 (CA)
Inventor: MALENFANT MARTIN
IPC: H05B44/00
Filed: 1997-12-17
Abstract: In a light-emitting-diode lamp, there is provided a circuit for simulating a low input impedance when the light-emitting-diode lamp is turned off. This low input impedance simulating circuit comprises a shunt circuit section, and a detector circuit section. The shunt circuit section includes a low impedance element and a controllable switching device connected in series. The detector circuit section detects turning off of the light-emitting-diode lamp and, in response to such detection, close the switching device to thereby cause electric current to flow through the shunt circuit section in order to simulate lower input impedance of the light-emitting-diode lamp. When the light-emitting-diode lamp replaces a conventional traffic signal incandescent lamp, the low input impedance simulating circuit prevents the conflict monitor of the already installed traffic-light lamp system to detect a high lamp impedance and accordingly a faulty lamp.

Title: Extraction dans l'eau chaude pour des sequences de blanchiment de pate
Inventor: PANGALOS GEORGE
IPC: D21C9/02
Filed: 1996-10-24
Abstract: Le recours à l'extraction dans l'eau chaude (pH 7-8, 165 ·F) à la place de l'extraction alcaline lors des séquences de blanchiment de pâte entre le lavage alcalin de l'étape de délignification à l'ozone et l'étape de blanchiment permet d'obtenir une pâte présentant une robustesse supérieure pour des degrés de blancheur pratiquement équivalents, tout en nécessitant des quantités globales réduites de produits chimiques de blanchiment. En outre, les eaux résiduaires provenant des étapes de lavage de la pâte qui suivent ces traitements peuvent être recyclées sans formation de tartre dans les équipements utilisés car la solubilité des sels susceptibles de former du tartre est nettement supérieure dans ces eaux résiduaires.
